“…These dissimilar results across regions, also differed from those found by other multitaxon studies (Beisner et al, 2006 ; De Bie et al, 2012 ; Gálvez et al, 2020 ; Padial et al, 2014 ), suggesting the impossibility to extract general patterns on environmental and spatial influence on metacommunity structure according to organism dispersal ability. Nevertheless, the results obtained for the mediterranean metacommunity are somehow in tune with those found in the abovementioned similar studies (e.g., stronger role of purely environmental effects in bacteria, phytoplankton, rotifers, microcrustaceans or macroinvertebrates than purely spatial effects), among others (Gálvez et al, 2022 ). By contrast, these patterns were much more diffuse in the tropical metacommunity, or even inverted.…”

“…Despite the large differences between several published studies, it seems that environmental selection is a proportionally stronger process than dispersal for the organization of freshwater metacommunities, especially in smaller organisms. However, some groups such as diatoms, ostracods, or macroinvertebrates show high variability in the role of these processes (Gálvez et al, 2022 ). Altogether, dispersal capacity, species traits, geographic variation in environmental features, and biogeographic context should interact in structuring metacommunities (please refer to Leibold et al, 2010 for a discussion).…”

The metacommunity concept provides a theoretical framework that aims at explaining organism distributions by a combination of environmental filtering, dispersal, and drift. However, few works have attempted a multitaxon approach and even fewer have compared two distant biogeographical regions using the same methodology. We tested the expectation that temperate (mediterranean-climate) pond metacommunities would be more influenced by environmental and spatial processes than tropical ones, because of stronger environmental gradients and a greater isolation of waterbodies. However, the pattern should be different among groups of organisms depending on their dispersal abilities. We surveyed 30 tropical and 32 mediterranean temporary ponds from Costa Rica and Spain, respectively, and obtained data on 49 environmental variables. We characterized the biological communities of bacteria and archaea (from the water column and the sediments), phytoplankton, zooplankton, benthic invertebrates, amphibians and birds, and estimated the relative role of space and environment on metacommunity organization for each group and region, by means of variation partitioning using generalized additive models.Purely environmental effects were important in both tropical and mediterranean ponds, but stronger in the latter, probably due to their larger limnological heterogeneity. Spatially correlated environment and pure spatial effects were greater in the tropics, related to higher climatic heterogeneity and dispersal processes (e.g., restriction, surplus) acting at different scales. The variability between taxonomic groups in the contribution of spatial and environmental factors to metacommunity variation was very wide, but higher in active,

“…Given that freshwater habitats are typically embedded within a terrestrial matrix, fluxes between terrestrial and aquatic environments, and among discrete aquatic habitats by faunal groups are catholic (Cuthbert et al, 2022; Knight et al, 2005). This is particularly relevant for mosaics of smaller water bodies, where metacommunity dynamics are characterized by a relatively large number of separate aquatic populations (Cuthbert et al, 2022; Gálvez et al, 2022).…”

Riverine ecosystems exhibit significant spatial variations in their communities, and understanding of these variances is vital to comprehend the mechanisms that maintain biodiversity. This study was conducted to understand pattern of distribution and beta diversity of fish communities in the Bhima River basin in the Deccan Plateau region of India. Fish distribution data from 59 sites across 11 rivers of the Bhima River basin were collected, and pair‐wise βDissimilarity and site‐wise local contribution to beta diversity (LCβDSorensen) and its components (LCβDTurnover and LCβDNestedness) were calculated. Power function regression was analysed to understand the decay in community similarity with geographical and environmental distances. Redundancy analysis was performed to investigate the relationship between fish distribution and environmental variables. Results indicated that species richness declined with increasing longitude from west to east. A negative relationship was observed between species richness and LCβDSorensen. LCβDTurnover formed Ո‐shaped curve at both ends of the species richness gradient, while LCβDNestedness values exhibited Ս‐shaped curve. No significant difference between mean LCβDTurnover and mean LCβDNestedness across the sites was observed. The distance decay relationship between community similarity and both geographical and environmental distances follows the power law shape, and the slope of this relationship flattened with increasing distance. Precipitation, topography, temperature variation and dissolved oxygen played a pivotal role in shaping fish assemblages. This study provides insight into the spatial distribution of fish communities in the Bhima River basin, which will be helpful to comprehend the ordination of biodiversity in the riverine ecosystem of the Deccan Plateau region.
